Concept Search - What can I type?

For a concept search, you can enter phrases, sentences, or full paragraphs in English. For example, copy and paste the abstract of a patent application or paragraphs from an article.

Concept search eliminates the need for complex Boolean syntax to inform retrieval. Our Semantic Gist engine uses advanced cognitive semantic analysis to extract the meaning of data. This reduces the chances of missing valuable information, that may result from traditional keyword searching.

Abstract

Disclosed is an interface mechanism between two communicating entities such as an I/O adapter card and its Device Driver (DD) which contains some key features addressing the following characteristics: discrimination between multi-type data frames, point-to-multipoint topology, congestion control, flow negotiation, data integrity checking. The following description assumes a DD-to-I/O card interface, but can be generalized to other types of interfaces.

Description of the Service Interface of the IBM Wireless
LAN Card

Disclosed is
an interface mechanism between two communicating
entities such as an I/O adapter card and its Device Driver (DD) which
contains some key features addressing the following characteristics:
discrimination between multi-type data frames, point-to-multipoint
topology, congestion control, flow negotiation, data integrity
checking. The following description
assumes a DD-to-I/O card
interface, but can be generalized to other types of interfaces.

The interface
is based on two communication mechanisms:
1.
A mail box mechanism that allows
a.
The DD to send 1 Byte to the adapter and interrupt the
microcode,
b.
the Microcode to send 1 Byte to the DD and interrupt the
microcode.
This Mechanism is used for
commands/control of the interface.
2.
A First In/First Out (FIFO) mechanism that used to send data
both
ways

The working
principle of this interface is the following:
When
the DD sends a frame to the adapter, it first signals it with a mail
box, then sends a header in the FIFO that indicates to the adapter
the type (Data,Control,network management) of the frame to be sent
(e.g., 1 byte), its size (e.g., 2 bytes), and the destination address
(e.g., 6 bytes), and then the actual frame to the FIFO. When the
Adapter sends a frame to the DD, it first signals it with a mail box,
then...
